It measures 0.281 inches in diameter and features a 135-degree split point that reduces walking on entry and lowers the force needed to start a hole. The high-speed steel construction handles the heat generated during sustained drilling. The Weldon flat shank with three flats provides positive drive and resists slipping in compatible chucks. This bit is suited for use by machinists, maintenance technicians, and metalworking tradespeople who need reliable, repeatable hole sizing in production or field repair environments.\u003c\/p\u003e\n\u003cp\u003eThis mechanics-length drill bit is intended for drilling carbon steel, cast iron, high alloy steel, high tensile strength alloys, and stainless steel. The shorter mechanics length gives better rigidity and control compared to jobber-length bits, making it a practical choice for tight-clearance work or applications where deflection must be minimized. The oxide finish provides a modest level of surface hardness and corrosion resistance for general shop and field use. It is sold individually with a minimum order quantity of 3.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e135-degree split point reduces drill walking and lowers entry force on hard materials\u003c\/li\u003e\n  \u003cli\u003eHigh-speed steel construction withstands heat buildup during metal drilling\u003c\/li\u003e\n  \u003cli\u003eWeldon flat shank with 3 flats prevents slippage in compatible chucks\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned parallel web improves chip evacuation and reduces thrust load\u003c\/li\u003e\n  \u003cli\u003eOxide finish adds surface hardness and basic corrosion protection\u003c\/li\u003e\n  \u003cli\u003eMechanics length provides increased rigidity over jobber-length equivalents\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in compatible Weldon flat shank drill chucks and holders.
